Kuvhiya Technique | "Kirschner Wire Tension Band Technique" yekugadziriswa kwemukati mukurapa kweBennett's Fracture.

Kutyoka kwaBennett kunoita 1.4% yekutyoka kwemaoko. Kusiyana nekutyoka kwakajairwa kwepasi pemapfupa emetacarpal, kutamiswa kweBennett kutyoka kwakasarudzika. Iyo proximal articular surface fragment inochengetedzwa munzvimbo yayo yepakutanga yeanatomical nekuda kwekudhonza kwe oblique metacarpal ligament, nepo distal fragment, nekuda kwekudhonza kweabductor pollicis longus uye adductor pollicis tendons, inobvisa dorsoradially uye supinates.

Nekutyoka kwaBennett kwakadzingwa, kurapwa kwekuvhiya kunowanzo kukurudzirwa kudzivirira kurongeka kweiyo carpometacarpal joint uye thumb function. Panyaya yekuvhiya nzira dzekurapa, ndiro uye screw fixation masisitimu, pamwe neKirschner wire mukati mekugadzirisa, inoshandiswa zvakanyanya mumakiriniki maitiro. Nyanzvi kubva kuChipatara Chechitatu cheHebei vakaronga nzira yeKirschner waya yetension bhendi, iyo inosanganisira diki diki yekuchekeresa kugadzirisa matyoka aBennett, kuwana mhedzisiro yakanaka.

Danho 1: Gadzira 1.3 cm incision paradial side ye carpometacarpal joint, dissetse layer by layer kuratidza nzvimbo, dzosera iyo abductor pollicis longus yakananga kudivi re ulnar, uye buritsa dorsal side ye carpometacarpal joint.

Danho rechipiri: Isa manyorerwo emaoko uye taura chigunwe kuti uderedze kutsemuka. Isa 1 mm Kirschner wire kuburikidza ne distal fracture end, 1-1.5 cm kure ne carpometacarpal joint, kugadzirisa proximal bone fragment. Mushure mekunge waya yeKirschner inopinda muchidimbu chepfupa, ramba uchiifambisa ne 1 cm.

Danho rechitatu: Tora waya woisungirira mumufananidzo-masere wakatenderedza magumo ese eKirschner waya, wozoichengetedza panzvimbo.

Iyo Kirschner waya tension bhendi tekinoroji yakashandiswa mukutyoka kwakawanda, asi kune kwakatyoka kwaBennett, iyo diki incision inowanzo konzera kusaoneka uye inoita kuti maitiro anetsa. Pamusoro pezvo, kana kuputsika kuchiitwa, imwe Kirschner waya inogona kusanyatso kudzikamisa iyo proximal bone fragment. Kushanda kwayo kwekiriniki kunogona kuve kwakaganhurirwa. Kunze kweiyo yambotaurwa tension bhendi nzira yekumisikidza, kune zvakare Kirschner waya yekumisikidza yakasanganiswa ne tension band tekinoroji, iyo yakashumwawo mumabhuku.
